检测是否在Inno Setup中安装了.NET Framework 4.6.2（或更高版本）

Question

此repository提供了有关部署.NET Microsoft Framework的指南。

我的Inno Setup脚本中有代码来检测是否安装了.NET Framework。这是我的功能：

function PrepareToInstall(var NeedsRestart: Boolean): String;
begin
  result := '';

  dotNetNeeded := not IsDotNetDetected();

  if(dotNetNeeded) then begin
    if (MsgBox(ExpandConstant('{cm:DotNet_NeedToDownload}'), \
                      mbConfirmation, MB_OKCANCEL) = IDCANCEL) then begin
      result := ExpandConstant('{cm:DotNet_InstallAborted}');
      Abort();
    end;
  end;
end;

// Determines if .NET 4.6.2 (or higher) is installed
function IsDotNetDetected(): boolean;
var
    strKey64: string;
    strKey86: string;
    release: cardinal;
    success: boolean;
    dwInstalled: cardinal;
begin
  strKey64 := 'SOFTWARE\Wow6432Node\Microsoft\NET Framework Setup\NDP\v4\Full';
  strKey86 := 'SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full';

  result := false; // Assume .NET Framework 4.6.2 is not installed

  // For more information, see:
  // http://msdn.microsoft.com/en-us/library/hh925568%28v=vs.110%29.aspx#net_b
  if(Is64BitInstallMode()) then begin
    if (RegValueExists(HKLM, strKey64, 'Release')) then begin
      RegQueryDWordValue(HKLM, strKey64, 'Release', dwInstalled);
      if(dwInstalled >= 378675) then begin
        result := true;
      end;
    end;
  end
  else begin
    if (RegValueExists(HKLM, strKey86, 'Release')) then begin
      RegQueryDWordValue(HKLM, strKey86, 'Release', dwInstalled);
      if(dwInstalled >= 378675) then begin
        result := true;
      end;
    end;
  end;
end;

我遇到了GitHub {{3}}

它具有以下功能：

// determines if .NET 4.7 is installed
function IsDotNetDetected(): boolean;
var
    key: string;
    release: cardinal;
    success: boolean;
    install: cardinal;
begin

    key := 'SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full';

    // check if the install bit is set
    success := RegQueryDWordValue(HKLM, key, 'Install', install);

    // and that the release number is greater than 460805, which is the version
    // that's bundled into the installer
    success := success and RegQueryDWordValue(HKLM, key, 'Release', release);
    success := success and (release >= 460805);

    result := success
end;

他们不检查Wow6432Node。那我要检查太多注册表项吗？
